BackgroundThe existing reports regarding the potential role of infections as well as antibiotic use in multiple sclerosis (MS) etiology are inconclusive. ObjectivesWe aimed to investigate the association of viral infections as well as antibiotic use and the risk of developing MS. Materials & methodsThis was a population-based incident case-control study of 547 incident cases and 1057 general population controls obtained from 22 municipality areas of Tehran (7/8/2013-17/2/2015). Multiple logistic regression models were used to determine the adjusted associations. ResultsOverall antibiotic use for 14days during 3years before the index date, significantly decreased the odds of MS OR 0.69 (95%CI: 0.53-0.91, P=.008). The results were consistent for different types of antibiotics, including penicillin OR 0.50 (95%CI: 0.34-0.75, P=.001) and cephalosporins OR 0.25 (95%CI: 0.12-0.50, P<.001). History of IM was associated with a more than 5fold increased risk of MS OR = 5.7 (95%CI, 1.28-25.37). There was no statistically significant association between any other single or cumulative number of viral infections with subsequent risk of MS (P>.05). ConclusionsConsidering the possibility of reverse causation, the results of this large case-control study suggest that use of antibiotics may be associated with a decreased risk of MS. However, viral disease other than infectious mononucleosis was not associated with MS risk.
